Solar powered chargers and cradles have a solar panel on them that collects energy when the charger is in direct sunlight. This energy is then used to power your compatible phone or other devices. The amount of time needed in the sun to fully charge your device depends on the power of the charger and your device’s battery. Most solar chargers connect directly to your device with a USB cable so that you can charge your device on the spot. There are many affordable options available on eBay.

What features should you look for in a solar charger?

There are several features that can make a charger more functional. To help you make the right choice for your needs, here is some information on optional features that can be found on some chargers on eBay:

  • Waterproof – Keeps the charger safe from the elements works well for camping and hiking
  • Flashlight – Provides you with a light source when you need it
  • Universal fit – Can be used for many different types of devices works well for groups or families
  • Dual ports – Allows you to charge two devices at once

The BigBlue 3 goes above and beyond the rest. Thanks to its impressive charging abilities and consistent performance across the board, this panel maintains its place at the top of the pack for another year. Though there may be other options out there that charge faster or look cooler, nothing beats this model when it comes to overall performance. When your electronics need a boost, this panel will deliver a consistent charge in variable conditions . In terms of features, we love the built-in ammeter and the zippered accessory pouch. We also appreciate this panel’s simplicity and reasonable price tag. With three USB ports and a classic fold-out design, the BigBlue is an excellent all-arounder that will efficiently charge most small gadgets.

One downside to this panel is its weight. Weighing in at 23.5 ounces, it’s a bit heavy. As a result, it’s better suited for front-country use, though it will excel wherever you use it. Other than its weight, this panel receives high marks across the board.

Make The Charger Pack

I wanted to be able to charge my phone while I was on the move so I made a custom pack to hang from my backpack, similar to the solarmonkey. I used an old lunch box my son doesn’t use anymore. It was just lying around collecting dust so I repurposed it for this project.

Whatever you use you will probably want a way to attach your solar panel and battery pack. For this I used sticky back velcro and it worked great. The lunchbox I used has a compartment for an ice pack, convenient for storing a cell phone in this case. I just cut a small hole for the USB cable to connect my cell phone to the battery pack. I can keep this pouch zipped up with my cell phone safely inside while the pack is open and charging.

Recommended Solar Phone Chargers

I have used at least a dozen solar charges over the past two years. Not all are made well, and many fell apart only after a few months of use. But the ones that hold up and work well, are really great to have as a backup when out in nature with no electricity available.

With that said, here are my four favorite solar phone chargers:

Limitations Of All Solar Phone Chargers

The biggest limitation of ALL solar phone chargers is also what makes them so great: the sun.

Without direct sunshine falling on your solar charger, its not going to charge your phone or will do so painfully slowly.

This is especially a bad problem for combo solar chargers that have integrated battery packs. They often include such low capacity solar panels that it would take days of perfect sunshine to recharge the battery.

Normally, you wont get perfect sunshine, even in the summer. Clouds can form, or you may be traveling through a thickly wooded area.

Thats why I recommend you get the highest wattage solar phone charger you can afford. It will charge your phone faster even with limited sun exposure time.

If you are planning to spend more than a couple of days in the wild, dont get an integrated solar charger+power bank unit. According to most campers, this type of integrated charger will frustrate you because of the low wattage solar panels, sometimes as low as 1 watt. Instead, get a high capacity solar-only charger and buy a couple of battery packs to charge with it.

Another issue with many solar phone chargers is their lack of versatility. They can only produce enough power for small devices.

Unlike larger portable solar chargers, you cannot use them to power your laptop, lamp or medical device.

The payoff is that you’ll get a charger small enough to put in your pocket.

Solar power banks are an essential for outdoor enthusiasts and offer a way to keep cell phones, cameras, and other gadgets charged when electricity is scarce. Theyre also invaluable when severe weather or power surges cause widespread outages.

These convenient, portable devices have evolved into several different styles, but the two most common are around the size of a cell phone and have either a single portable solar panel or several expanding, folding panels. Solar chargers with one panel are more compact, but also slower to recharge using the suns energy. Multiple panels can speed things up a bit but are often bulkier. The fastest way to recharge both is by plugging a USB into a traditional power source and storing the energy. Once the power bank has been replenished, various electronics can still be charged on the device indoors or at night.

Here are the best solar power banks, many with added features such as wireless charging, waterproof exteriors, and built-in flashlights.
